Faucaria tuberculosa, or Pebbled Tiger Jaws, is a clump-forming, perennial succulent native to the Cape Province of South Africa. The opposite dark green leaves are ovate-triangular in the top view and will reach 1 inch (2.5 cm) long by 0.75 inches (2 cm) wide. The upper side is covered in white tubercles, the margins with small white dots with 3 stout teeth and several smaller teeth. Plants are very easy to grow.
Blooming: In the greenhouse, Faucaria tuberculosa blooms in late spring to early summer. The yellow flowers are 1.5 inch (3.8 cm) across and very showy.
Culture: Faucaria tuberculosa need full sun to light shade with a well-drained soil mix. In the greenhouse, we use a soil mix consisting of 2 parts coarse sand to 1 part peat moss to 1 part loam. The plants are well watered and allowed to dry thoroughly before watering again. Any fertilizer used should be diluted to 1/4 the strength recommended on the label. During the winter months, the plants should be kept very dry -- only watering enough to keep the leaves from shriveling. Winter temperatures should not fall below 58°F (18°C), or cold injury to the plant could result.
Propagation: Faucaria tuberculosa is very easy to start from seed. Seeds germinate in 7-14 days at 70°F (21°C). Although they will start from cuttings, it is very difficult to get them to root.
